Entity Framework
Also written as EF Core, Entity Framework Core
The standard ORM for .NET/C#: it lets developers work with database tables as C# objects instead of writing SQL by hand.
Think of it like
An interpreter between C# code and the database, so neither has to learn the other's language.
Junior or senior?
Near-universal on .NET resumes.
Senior sounds like
Knows when EF generates slow queries and when to drop down to raw SQL.
Ask them
“When did Entity Framework generate a slow query for you, and what did you do about it?”
